Think it's also in response to the number of people I've seen that were throwing one towel in the bin and grabbing 3 clean towels. I even heard a very nicely dressed woman say to her small child, when the child asked why they were getting 3 towels, "one's for Daddy and Mommy's taking these to the room to put in the luggage."..stealing them. This will just keep everyone a little more honest and will cut down on the chair hogs out by the pool.
